Single-agent ibrutinib in RESONATE-2™ and RESONATE™ versus treatments in the real-world PHEDRA databases for patients with chronic lymphocytic leukemia.

After analyzing treatment patterns in chronic lymphocytic leukemia (CLL) (objective 1), we investigated the relative effectiveness of ibrutinib versus other commonly used treatments (objective 2) in patients with treatment-naïve and relapsed/refractory CLL, comparing patient-level data from two randomized registration trials with two real-world databases. Hazard ratios (HR) and 95% confidence intervals (CIs) were estimated using a multivariate Cox proportional hazards model, adjusted for differences in baseline characteristics. Rituximab-containing regimens were often prescribed in clinical practice. The most frequently prescribed regimens were fludarabine + cyclophosphamide + rituximab (FCR, 29.3%), bendamustine + rituximab (BR, 17.7%), and other rituximab-containing regimens (22.0%) in the treatment-naïve setting (n = 604), other non-FCR/BR rituximab-containing regimens (38.7%) and non-rituximab-containing regimens (28.5%) in the relapsed/refractory setting (n = 945). Adjusted HRs (95% CI) for progression-free survival (PFS) and overall survival (OS), respectively, with ibrutinib versus real-world regimens were 0.23 (0.14-0.37; p < 0.0001) and 0.40 (0.22-0.76; p = 0.0048) in the treatment-naïve setting, and 0.21 (0.16-0.27; p < 0.0001) and 0.29 (0.21-0.41; p < 0.0001) in the relapsed/refractory setting. When comparing real-world use of ibrutinib (n = 53) versus other real-world regimens in relapsed/refractory CLL (objective 3), adjusted HRs (95% CI) were 0.37 (0.22-0.63; p = 0.0003) for PFS and 0.53 (0.27-1.03; p < 0.0624) for OS. This adjusted analysis, based on nonrandomized patient data, suggests ibrutinib to be more effective than other commonly used regimens for CLL.

Sustained virological response with telaprevir in 1,078 patients with advanced hepatitis C: the international telaprevir access program.

BACKGROUND & AIMS: There is little information regarding the extent to which difficult to cure patients with advanced liver fibrosis, due to hepatitis C virus genotype-1 (HCV-1) can successfully and safely be treated with triple therapy with telaprevir (TVR), pegylated interferon alpha (P) and ribavirin (R). In the TVR early access program HEP3002 we aimed to explore treatment safety and efficacy, and identify predictors of sustained virological response at week 24 (SVR24). METHODS: 1078 patients with bridging fibrosis (n=552) or cirrhosis (n=526) diagnosed by either liver biopsy or non-invasive markers, with compensated bone marrow (neutrophils >1500/mm(3), Hb >12/13 g/dl) and liver function (Albumin >3.3g/dl, Platelets >90,000/ml) received TVR PR for 12 weeks, followed by a PR tail according to label. RESULTS: Overall, 614 (57%) achieved SVR24 by intention-to-treat analysis. The SVR24 rate was 68% in 221 treatment naïve patients (62.8% F4), 72% in 356 prior relapsers (64.4% F4), 55% in 139 partial responders (53.2% F4), and 34% in 294 null responders (28.6% F4). The SVR24 rate to response-guided therapy (24 weeks treatment duration if undetectable viremia at weeks 4 and 12) was 84% in 222 naïve/relapser F3 patients. Independent predictors of response were: (A) F3 (odds ratio (OR)=1.51, 95% CI 1.31-2.00, p=0.005), (B) subtype 1b (OR=1.63, 95% CI 1.18-2.24, p=0.0029), (C) alpha-fetoprotein <10 ng/ml (OR=2.50, 95% CI 1.87-3.36, p<0.0001) and (D) any prior response other than null (OR=3.29, 95% CI 2.40-4.52, p<0.0001). SVR24 rose for patients who had more of these predictive factors: 6/32 (19%) for none, 38/139 (27%) for 1, 129/260 (50%) for 2, 202/329 (61%) for 3, and 194/235 (83%) for 4 factors. Grade 2-4 treatment-related adverse events (AE) were experienced by 719 (67%) patients; 169 (16%) discontinued therapy for AE and 7 (0.6%) died during the PR tail. CONCLUSIONS: Naïve and experienced patients with advanced fibrosis or cirrhosis due to HCV-1 who have compensated bone marrow and liver function, can effectively and safely be treated by TVR triple therapy. Baseline predictors of outcome have been identified to optimize pre-treatment counselling.

The Burden of a Multiple Myeloma Diagnosis on Patients and Caregivers in the First Year: Western European Findings.

Background: This research aimed to quantify the burden of illness (BoI) in transplant eligible (TE) and transplant non-eligible (TNE) newly diagnosed multiple myeloma (NDMM) patients and their caregivers, in the first year after diagnosis: at months 0, 3, and 12. Methods: Prospective, cross-sectional, observational NDMM study of TE and TNE patients and their caregivers from France, Germany, Italy, and Spain was conducted between May 2019 and January 2021. A structured, online questionnaire measuring disease burden, direct and costs, out-of-pocket expenses, and health-related quality of life (HRQoL) was used. Descriptive statistics were performed. Results: A total of 164, 160, and 190 NDMM patients [>65 years; self-described healthy; not working; living with caregiver] answered at months 0, 3, and 12. Patients lost independence to perform daily activities; mean pain intensity rose and opioid utilization increased, more significantly among TNE patients. Overall health status and HRQoL remained stable. Median 3-month direct medical costs peaked at month 3. Specialist consultations and hospital admissions were the greatest cost amongst TE and TNE patients. Home adaptations increased out-of-pocket expenditures amongst TNE patients. Patients describing themselves as working spent a median 0 hours in the office at all time points. A total of 131, 122, and 124 caregivers answered at months 0, 3, and 12. Mean self-rated burden score rose. By month 12, half of caregivers developed stress, anxiety or depression. Most employed caregivers continued working. Productivity was low at month 0 with a trend of recovering at month 12. Caregivers of TNE compared to TE patients reported greater time burden. Caregivers' HRQoL was stable over time. Conclusion: NDMM is burdensome for patients and caregivers in the first year after diagnosis. TNE patients are more dependent on caregivers and incur higher care costs than TE patients. Despite the financial, physical, and emotional burden, HRQoL remains stable possibly indicating resilience and illness adjustment amongst patients and caregivers.

Daratumumab Monotherapy for Relapsed or Refractory Multiple Myeloma: Results of an Early Access Treatment Protocol in Europe and Russia.

INTRODUCTION: Daratumumab is a human IgGκ monoclonal antibody targeting CD38. Despite the demonstrated benefit of daratumumab in multiple myeloma, not all patients have access to commercially available daratumumab. Here we report a pooled analysis of patients from the UK, Spain, Italy, and Russia enrolled in an open-label, early access treatment protocol (EAP) that provided daratumumab (16 mg/kg) monotherapy to patients with heavily pre-treated relapsed or refractory multiple myeloma (RRMM). METHODS: Intravenous daratumumab 16 mg/kg was administered to patients who had received ≥ 3 prior lines of therapy, including a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD), or who were double refractory to both a PI and an IMiD. Safety and patient-reported outcomes data were collected. RESULTS: A total of 293 patients received ≥ 1 dose of daratumumab. The median duration of daratumumab exposure was 4.2 (range 0.03-24.1) months, with a median number of 13 (range 1-37) infusions. The overall response rate was 33.1%, and the median progression-free survival was 4.63 months. Grade 3/4 treatment-emergent adverse events occurred in 60.1% of patients, of which the most common were thrombocytopenia (18.8%), anemia (11.9%), and neutropenia (11.6%). The most common serious adverse events were pneumonia (4.4%) and pyrexia (4.1%). Infusion-related reactions occurred in 45.1% of patients. The median change from baseline in all domains of patient-reported outcome instruments (European Quality of Life Five Dimensions Questionnaire [EQ-5D-5L], European Organisation for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [QLQ-C30], and EORTC Multiple Myeloma Module [QLQ-MY20]) was generally 0 or close to 0. CONCLUSION: These EAP results are consistent with those from previous trials of daratumumab monotherapy and confirm its safety in patients from Europe and Russia with heavily pre-treated RRMM.

Extracellular cardiac matrix biomarkers in patients with acute myocardial infarction complicated by left ventricular dysfunction and heart failure: insights from the Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS) study.

BACKGROUND: Aldosterone stimulates cardiac collagen synthesis. Circulating biomarkers of collagen turnover provide a useful tool for the assessment of cardiac remodeling in patients with congestive heart failure and left ventricular systolic dysfunction after acute myocardial infarction. METHODS AND RESULTS: In a substudy of the Eplerenone Post-Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS), which evaluated the effects of the selective aldosterone receptor antagonist eplerenone versus placebo, serum levels of collagen biomarkers were measured in 476 patients with congestive heart failure after acute myocardial infarction complicated with left ventricular systolic dysfunction. The combination of the type I collagen telopeptide and brain natriuretic peptide levels above median at baseline was associated with all-cause mortality and the composite end point of cardiovascular death or heart failure hospitalization, with hazard ratios of 2.49 (P=0.039) and 3.03 (P=0.002), respectively. During follow-up, levels of aminoterminal propeptide of type I and type III procollagen were found to be consistently lower in the eplerenone group and significantly lower beginning at 6 months. CONCLUSIONS: Changes in biomarkers of collagen synthesis and degradation suggest that extracellular matrix remodeling is an active process in patients with congestive heart failure and left ventricular systolic dysfunction after acute myocardial infarction. High type I collagen telopeptide and high brain natriuretic peptide serum levels are associated with the highest event rate. Eplerenone suppresses post-acute myocardial infarction collagen turnover changes.

Extracellular matrix fibrotic markers in heart failure.

Given the importance of fibrous tissue in leading to myocardial dysfunction, non-invasive assessment of fibrosis could prove a clinically useful tool in heart failure (HF) patients. Biomarkers may be used for early detection of otherwise subclinical disease, diagnostic assessment of an acute or chronic clinical syndrome, risk stratification of patients with a suspected or confirmed diagnosis, selection of an appropriate therapeutic intervention and monitoring the response to therapy. Extracellular matrix (ECM) biomarkers in HF are promising biomarkers. They are able to detect early changes in heart and large vessel structure and function and transition to HF. High ECM biomarker levels have been associated with poor outcome. The ability of treatment to reduce myocardial fibrosis in HF patients may be monitored by the measurement of various serum peptides arising from the metabolism of collagen types. Biomarkers may be selectively influenced by pharmacological agents.

A multifactorial strategy of pain management is associated with less pain in scheduled vaccination of children. A study realized by family practitioners in 239 children aged 4-12 years old.

BACKGROUND AND AIMS: The multiplicity of vaccine injections during childhood leads to iterative painful and stressful experiences which may lead in turn to anticipated pain and then possibly to a true needle phobia. We aimed at evaluating a multifactorial strategy of pain management combining pharmacological and non-pharmacological approaches during vaccination, as compared to usual care, in 4- to 12-year-old children. METHODS: In all, 239 children were enrolled by 25 family practitioners in an open-label study. After a pseudo-randomization, usual pain management (n = 132) was compared to a multifactorial strategy (n = 107) associating preliminary application of an anesthesic patch, preferential use of specified vaccines, child education by the parents and the doctor, parental accompaniment and child distraction with soap bubbles during the procedure. The primary outcome (i.e. child pain) was assessed with a self-report scale named visual analog scale (VAS) of pain. RESULTS: A significant decrease in pain was obtained using the multifactorial strategy, as assessed by self-reported VAS (P < 0.0001). This was confirmed by another self-report scale (the facial pain scale revised: P = 0.005), as well as with hetero-evaluations by GPs and parents [Children's Hospital of Eastern Ontario Pain Scale: P = 0.0007; GPs VAS (P < 0.0001), parents VAS (P < 0.0001)], which were secondary outcome criteria. CONCLUSIONS: This multifactorial method significantly decreases vaccination pain in 4- to 12-year-old children. This strategy could make vaccines more acceptable to children and may improve child-doctor relationships and contribute to a decrease in child fear about health care.

PHEDRA: using real-world data to analyze treatment patterns and ibrutinib effectiveness in hematological malignancies.

AIM: PHEDRA (Platform for Haematology in EMEA: Data for Real World Analysis) is a unique, noninterventional project based on secondary data collection from real-world (RW) patient-level (health record) databases to understand treatment patterns in hematological malignancies. It compares ibrutinib's effectiveness with alternative treatments using RW data (RWD) and randomized clinical trials data. MATERIALS & METHODS: RWD are cleaned, validated, harmonized into a Common Data Model, and analyzed statistically alongside randomized clinical trial data. Treatment outcomes include overall and progression-free survival. RESULTS: To date, RWD (four databases) are available for 2840 patients in three indications, collected between 1990 and 2017. CONCLUSION: PHEDRA is an innovative approach to generate evidence to inform optimal treatment decisions in RW settings.

Final Results of the Telaprevir Access Program: FibroScan Values Predict Safety and Efficacy in Hepatitis C Patients with Advanced Fibrosis or Cirrhosis.

BACKGROUND: Liver stiffness determined by transient elastography is correlated with hepatic fibrosis stage and has high accuracy for detecting severe fibrosis and cirrhosis in chronic hepatitis C patients. We evaluated the clinical value of baseline FibroScan values for the prediction of safety and efficacy of telaprevir-based therapy in patients with advanced fibrosis and cirrhosis in the telaprevir Early Access Program HEP3002. METHODS: 1,772 patients with HCV-1 and bridging fibrosis or cirrhosis were treated with telaprevir plus pegylated interferon-α and ribavirin (PR) for 12 weeks followed by PR alone, the total treatment duration depending on virological response and previous response type. Liver fibrosis stage was determined either by liver biopsy or by non-invasive markers. 1,282 patients (72%) had disease stage assessed by FibroScan; among those 46% were classified as Metavir F3 at baseline and 54% as F4. RESULTS: Overall, 1,139 patients (64%) achieved a sustained virological response (SVR) by intention-to-treat analysis. Baseline FibroScan values were tested for association with SVR and the occurrence of adverse events. By univariate analysis, higher baseline FibroScan values were predictive of lower sustained virological response rates and treatment-related anemia. By multivariate analysis, FibroScan was no longer statistically significant as an independent predictor, but higher FibroScan values were correlated with the occurrence of infections and serious adverse events. CONCLUSIONS: FibroScan has a limited utility as a predictor of safety and efficacy in patients treated with telaprevir-based triple therapy. Nevertheless it can be used in association with other clinical and biological parameters to help determine patients who will benefit from the triple regiments.

Association of galectin-3 and fibrosis markers with long-term cardiovascular outcomes in patients with heart failure, left ventricular dysfunction, and dyssynchrony: insights from the CARE-HF (Cardiac Resynchronization in Heart Failure) trial.

AIMS: Circulating biomarkers of collagen turnover reflect extracellular cardiac matrix (ECCM) remodelling. The extent to which the success of cardiac resynchronization therapy (CRT) is influenced by the degree of cardiac fibrosis and whether CRT can influence matrix remodelling has yet to be studied. Our aim was to determine, in patients with heart failure (HF) and cardiac dyssynchrony, whether ECCM biomarkers are influenced by CRT and can predict cardiovascular outcomes and response to CRT. METHODS AND RESULTS: Serum levels of ECCM biomarkers [galectin-3 (Gal-3), N-terminal propeptides of type I and III procollagens (PINP and PIIINP), type I collagen telopeptide (ICTP), and matrix metalloproteinase 1 (MMP-1)] were measured in 260 patients, in a substudy of CARE-HF, a randomized controlled trial which evaluated the effects of CRT in patients with left ventricular systolic dysfunction and cardiac dyssynchrony. ECCM biomarkers did not change throughout the 18-month follow-up period. In age- and gender-adjusted analyses, Gal-3 and PIIINP were associated with death or HF hospitalization. In a further multivariate model, Gal-3 >30 ng/mL was associated [OR (95% CI):2.98 (1.43-6.22), P = 0.004] with death or HF hospitalization, along with left ventricular end-systolic volume >200 mL [3.42 (OR: 1.65-7.10), P = 0.001]. The outcome death or left ventricular ejection fraction (LVEF) ≤35% was associated with MMP-1 [≤3 ng/mL: 3.04 (1.37-6.71), P = 0.006]. No significant interaction was observed between the tested biomarkers and the treatment group. CONCLUSIONS: Increased Gal-3 and PIIINP, and low MMP-1 are associated with adverse long-term cardiovascular outcomes but did not predict response to CRT. CRT did not favourably affect serum concentrations of ECCM markers.

A uniform activated B-cell-like immunophenotype might explain the poor prognosis of primary central nervous system lymphomas: analysis of 83 cases.

Most primary central nervous system lymphomas (PCNSLs) in immunocompetent patients are diffuse large B-cell lymphomas (DLBCLs), characterized by poor prognosis, compared with systemic forms. A germinal center B-cell-like (GCB) origin of PCNSL was hypothesized on the basis of BCL-6 expression and ongoing mutational activity. Our goal herein was to determine, for 83 PCNSLs, the percentages of GCB and activated B-cell-like (ABC) phenotypes and their prognostic significance. CD10, BCL-6, MUM1, BCL-2, and CD138 antigens were immunohistochemically labeled on paraffin-embedded sections; the first 4 were positive in 2.4%, 55.5%, 92.6%, and 55.5% of the tumors, respectively. None of the 56 tested samples expressed CD138. Among the 82 patients with complete information, 79 (96.3%) were classified as ABC; 42 (51.2%) expressed BCL-6+ MUM1+, suggesting an "activated GCB" origin; 33 (40.2%) were exclusively MUM1+, and the remaining 4 (4.9%) were negative for all markers tested. These findings provide new insights into interpreting the poor PCNSL prognostic, which may, in part, be due to biologic aggressiveness associated with its activated B-cell-like pattern. We postulate assigning PCNSL a histogenetic "time-slot," overlapping late GC and early post-GC, that could explain the predominant ABC phenotype observed.
